Let the two numbers be represented by x and y respectively.
Then x + y = 23, and x - y = 5.
Solve this system of linear equations for x and y. Start by rearranging them vertically:
x + y = 23
x - y = 5
--------------- Combining the two equations eliminates y:
2x = 28.
Then x = 14. If x = 14, then 14 + y = 23, and y = 9..
The solution is (14, 9); that is, x = 14 and y = 9.
So since he eats a pound of food when he weighs 3 ounces he eats about 5 and 1/3 times more than his own size. That means if we ate like shrews and we weighed 80 pounds we would eat about 426 pounds of food.
answer:
39.9
Step-by-step explanation:
54= area of rectangle
28.26= area of the circle
divide circle area by 2
= 14.13
subtract half of circle from rectangle area
54- 14.13
= 39.9
